The argument you are making here is that somebody else will figure it out. However, the argument you made before depends on that any arbitrary entity will figure it out with time and money. Those are categorically different.
If, in the first place, you actually meant that somebody else will figure it out, then it is logically unsound to argue that a arbitrarily chosen entity, Tesla in this case, is a shoe-in to figure it out as well. You need to present actual arguments for why they in particular will be a somebody.
If you actually thought the argument you presented initially was logically sound, then you meant everybody and the arguments you have just made are irrelevant as they only argue “there exists”, not “for all” which is what your initial argument rested on.
tl;dr You are mixing up “there exists” and “for all”.
